Based on: Speculative
Metaculus assigns Republicans 58.9% probability of holding the most Senate seats – implying ≈41% for Democrats. Structural analysis: Republicans currently hold a 53-47 majority and must defend 22 of the 35 contested seats. Democrats need a net gain of four seats. The NYT recently upgraded Alaska from 'Lean Republican' to 'Tossup'. Democrats lead in North Carolina and Maine; Republicans hold narrow advantages in Iowa, Ohio, and Texas. Historical anti-Trump wave effect (the president's party typically loses seats in midterms) could boost chances. Headwind: the Senate map structurally favors Republicans in this specific cycle composition.
Data basis for this prediction

Brent Crude surged to an intraday high of $87.37 (+4.8%) on July 15, 2026, triggered by a US naval blockade on Iranian vessels and reports of strikes on Gulf energy infrastructure (Forbes Advisor). Iran declared the Strait of Hormuz officially closed. The EU, as a major Middle East oil importer, is directly affected. Historically, EU Iran sanctions packages followed US measures with a 2–6 week lag (2012, 2019). The open US OFAC secondary sanctions prediction (by July 25) increases pressure on the EU to act in parallel. The EU could also target shadow fleet operations (analogous to Russia sanctions). Counterweight: the EU seeks to keep diplomatic channels open. Probability: 40%.

The DPFP is a centrist economic-reform party especially popular with younger voters (platform: wage increases, household relief). In the 2025 Sangiin election, the DPFP won 17 seats, raising its total to 22. In the February 2026 Shugiin election, the party defended 28 seats in the lower house. CSIS analyses point to a fragmented opposition landscape in which several smaller parties gain at the expense of LDP and Komeito. Japan Times reported high DPFP support in February 2026 polling. No Polymarket market found for DPFP seat count. Historical momentum and sustained popularity support ≥15 seats; risk: vote concentration among other opposition parties (Reiwa, Ishin).

Multiple market reports indicate that Andy Burnham, currently Greater Manchester Mayor, will be sworn in as UK Prime Minister on July 20, 2026, as Keir Starmer steps down. Sterling gained +0.29% on July 14 (GBP/USD: 1.3387), with analysts partly attributing this to the expected political reset under Burnham. An existing open Cassandra prediction ('GBP/USD above 1.3500 on July 31, 2026') explicitly cites Burnham as a price driver — embedding his succession as a market expectation. Labour's House of Commons majority secures the transfer of power without a general election; no known constitutional obstacle.
